Abstract

The invention relates to a self-retaining permanently tensionable synthetic tie for use in surgery and orthopaedics. It comprises a tensioning nipple passed through by a tie channel in the longitudinal direction, a permanently elastic synthetic tie which can be guided through the tie channel and essentially fills the latter, and blocking devices which prevent the synthetic tie, even under tensile stress, by narrowing the tie channel, from moving counter to the direction of passing through. The synthetic tie and tensioning nipple consist of resorbable or permanently compatible material.

Description

Die Erfindung betrifft ein dauerspannbares Kunststoffband mit Selbsthalterung zur Verwendung in Chirurgie und Orthopädie.The invention relates to a permanently stretchable plastic band with a self-holder for use in surgery and orthopedics.

Es ist seit langem bekannt, für Operationen im unfallchirurgischen und orthopädischen Bereich Metalldrähte für Zuggurtungen und Cerclagen zu verwenden.It has long been known to use metal wires for tension belts and cerclages for operations in the trauma surgical and orthopedic field.

Bei der Cerclage umschließt ein Draht reponierte Knochenfragmente und hält sie temporär oder dauernd zusammen. Die Zuggurtung soll muskuläre Zugspannungen und Belastungskräfte neutralisieren.In cerclage, a wire encloses repositioned bone fragments and holds them together temporarily or permanently. The tensioning straps are intended to neutralize muscular tension and load forces.

Der seit über hundert Jahren dafür gebräuchliche Bindedraht beweist insbesondere bei der konventionellen Zuggurtung zusätzlich zu den biomechanischen Mängeln Nachteile auf, die auf seinen mechanischen Eigenschaften beruhen. Er bewirkt keine funktionelle Stabilität; Festigkeit des Knochen-Metallverbundes durch Kompression wäre mit Draht nur erreichbar, wenn dieser dauerhaft vorgespannt werden könnte. Das ist nicht erreichbar, da der Bindedraht relativ steif und unelastisch ist und sich bereits bei Belastungen von 200 N/mm 0 1 mm streckt. Zudem können die Drahtenden nur schlecht miteinander verbunden werden. Durch Verdrehen der Enden läßt sich Bindedraht nicht spannen, weil er sich im Zwirbel dehnt und keine Zugkraft weitergeben kann. Bricht der Draht im Zwirbel, muß neu reponiert werden. Bindedraht ist daher für Cerclagen und wirksame Zuggurtungen nur wenig geeignet.The binding wire, which has been used for over a hundred years, demonstrates disadvantages, in particular in the case of conventional drawstring, in addition to the biomechanical defects, which are based on its mechanical properties. It does not bring about functional stability; Strength of the bone-metal bond through compression would only be achievable with wire if it could be permanently prestressed. This cannot be achieved because the binding wire is relatively stiff and inelastic and already stretches at loads of 200 N / mm 0 1 mm. In addition, the wire ends are difficult to connect. By twisting the ends, the binding wire cannot be tensioned because it stretches in the swirl and cannot transmit any tensile force. If the wire breaks in the swirl, it must be repositioned again. Tie wire is therefore not very suitable for cerclages and effective tension strapping.

Zur Überwindung dieser Nachteile wurde in neuerer Zeit die Seilosteosynthese eingeführt, die zum ersten Mal praktisch brauchbare Zuggurtungen bei Operationen zugänglich machte. Nach dieser von Labitzke entwickelten Methode werden zur Aufbringung der Zugkraft Drahtseile verwendet, die sich kontrollierbar spannen und befestigen lassen. Die Drahtseile werden mit einer plombenähnlichen Preßklemme unter Spannung gehalten. Jedoch ergibt sich bei Cerclagen mit Drahtseilen das Problem, daß durch die notwendige Materialdicke der zur Anpressung der Preßklemme an die Drahtseile notwendigen Zange die Preßklemme beim Preßvorgang nicht am Knochen anliegt. Nach Entfernen der Zange fällt die Preßklemme auf die Kortikalis herab. So entsteht ein Abstand der Cerclage vom Knochenumfang, so daß die Cerclage zu weit wird. Entsprechend läßt die interfragmentäre Kompression nach oder geht sogar ganz verloren. Zur Vermeidung dieses Nachteils ist es notwendig, spezielle Seilbrücken zwischen dem Cerclageseil und der Knochenoberfläche einzusetzen.To overcome these disadvantages, rope osteosynthesis has recently been introduced, which for the first time made practically usable tension straps accessible during operations. According to this method developed by Labitzke, wire ropes are used to apply the tensile force, which can be tensioned and fastened in a controllable manner. The wire ropes are kept under tension with a seal-like clamp. However, the problem arises with cerclages with wire ropes that due to the necessary material thickness of the pliers necessary for pressing the ferrule against the wire ropes, the ferrule does not rest on the bone during the pressing process. After removing the forceps, the pressure clamp drops onto the cortex. This creates a distance between the cerclage and the circumference of the bone, so that the cerclage becomes too wide. Correspondingly, the interfragmentary compression subsides or is even completely lost. To avoid this disadvantage, it is necessary to use special rope bridges between the cerclage rope and the bone surface.

Die Seilosteosynthese bietet zwar gegenüber der herkömmlichen Cerclage- und Zuggurtungs-Osteosynthese mit Bindedraht bereits Verbesserungen, erfordert jedoch zur Verankerung der Drahtseile am Knochen das Einsetzen von über dessen Außenumfang vorstehenden Schrauben. Auch die Seilschuhe und Preßklemmen sowie die nach Verspannen und Abschneiden der Drahtseile stehenbleibenden Seilenden stehen über die Knochenaußenfläche vor, was zu Komplikationen führen kann. Auch läßt die Biokompatibilität der verwendeten Metallwerkstoffe zu wünschen übrig. Außerdem ist die Seilosteosynthese hinsichtlich der verwendeten Materialien wie auch ihrer operativen Verwendung aufwendig.Although rope osteosynthesis already offers improvements over conventional cerclage and tension belt osteosynthesis with binding wire, it requires the insertion of screws projecting beyond its outer circumference in order to anchor the wire ropes to the bone. The rope shoes and compression clamps as well as the rope ends that remain after tensioning and cutting off the wire ropes also protrude beyond the outer surface of the bone, which can lead to complications. The biocompatibility of the metal materials used also leaves something to be desired. In addition, rope osteosynthesis is complex in terms of the materials used and their operational use.

Zur Verbesserung der Biokompatibilität sollte statt der bekannten metallischen Materialien ein Kunststoffmaterial verwendet werden, wie es beispielsweise seit langem in der Gefäßchirurgie benutzt wird.To improve the biocompatibility, a plastic material should be used instead of the known metallic materials, as has been used for a long time in vascular surgery, for example.

Aufgabe der Erfindung ist es daher, ein Kunststoffband der eingangs genannten Art zu schaffen, das unaufwendig herstellbar und operativ anwendbar ist und ohne nachfolgende Komplikationen eine zuverlässige bleibende Zugspannung auf die in Position zu fixierenden Teile auszuüben gestattet.It is therefore an object of the invention to provide a plastic band of the type mentioned at the outset, which is inexpensive to produce and can be used operationally and which permits reliable permanent tension to be exerted on the parts to be fixed in position without subsequent complications.

Zur Lösung dieser Aufgabe ist das dauerspannbare Kunststoffband der eingangs genannten Art erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs 1 definierten Merkmalen ausgestattet.To achieve this object, the permanently stretchable plastic band of the type mentioned is equipped according to the invention with the features defined in the characterizing part of patent claim 1.

Das erfindungsgemäße Kunststoffband besteht aus biokompatiblen Materialien, die entweder vom Körper resorbiert werden oder auch bei dauerndem Verbleib im Körper störungsfrei kompatibel sind. Das Kunststoffband.im angespannten Zustand haltende Spannmittel kann in den Knochen versenkt werden, so daß kein überstehen mit den entsprechenden Funktionsstörungen auftreten kann. Das Kunststoffband eignet sich sowohl für Cerclagen wie auch für Zuggurtungen. Damit ist auch bei unzugänglichen Knochenabschnitten eine feste Verbindung möglich und eine groß angelegte Knochenfreilegung kann unterbleiben.The plastic tape according to the invention consists of biocompatible materials which are either resorbed by the body or are compatible without interference even if they remain in the body for a long time. The plastic band holding the tensioning device in the tensioned state can be sunk into the bone, so that no overcoming with the corresponding malfunctions can occur. The plastic tape is suitable for cerclages as well as for tension tapes. This enables a firm connection even with inaccessible bone sections and large-scale bone exposure can be avoided.

Vorteilhafte weitere Ausgestaltungen des Kunststoffbandes sind in den Unteransprüchen 2 bis 11 angegeben.Advantageous further developments of the plastic band are specified in subclaims 2 to 11.

Nach der in den Ansprüchen 2 bis 9 definierten, bevorzugten Ausführungsform des Kunststoffbandes wird dieses durch eine Durchbohrung geführt, die die zu verbindenden Knochenfragmente durchsetzt. Die an einem Ende des Kunststoffbandes vorgesehene Verdickung tritt beim Anspannen des Kunststoffbandes teilweise in die Durchbohrung ein und bildet ein die Zugspannung auf das Knochenfragment übertragendes Gegenlager. Am anderen Ende der Durchbohrung tritt das-das Kunststoffband unter Spannung haltende Spannmittel ebenfalls in die Durchbohrung ein. Nachdem die gewünschte Zugspannung erreicht ist, können die überstehenden Teile von Verdickung und Spannippel mit der Knochenaußenfläche fluchtend abgeschnitten werden, so daß sich trotz zugfester Verbindung der Knochenfragmente kein störender Überstand ergibt. Bei der in den Ansprüchen 10 und 11 beschriebenen bevorzugten Ausführungsform umgreift das Kunststoffband den Knochenaußenumfang; der Spannippel kann leicht in den Knochen versenkt werden und tritt durch seine abgeflachte Außenfläche kaum über dessen Außenumfang vor.According to the preferred embodiment of the plastic band defined in claims 2 to 9, it is passed through a through-hole which passes through the bone fragments to be connected. The thickening provided at one end of the plastic band partially enters the through-hole when the plastic band is tightened and forms a counter bearing that transmits the tensile stress to the bone fragment. At the other end of the through-hole, the tensioning means holding the plastic band also enters the through-hole. After the desired tensile stress has been reached, the protruding parts of the thickening and clamping nipple can be cut flush with the outer surface of the bone, so that despite the tensile connection of the bone fragments there is no disruptive protrusion. In the preferred embodiment described in claims 10 and 11, the plastic band encompasses the outer circumference of the bone; the clamping nipple can be easily sunk into the bone and, due to its flattened outer surface, hardly protrudes beyond its outer circumference.

Das erfindungsgemäße dauerspannbare Kunststoffband kann in der Chirurgie des Haltungs- und Bewegungsapparates z.B. in folgenden Fällen verwendet werden:

  • Provisorische Fixierung von Frankturen (z.B. bei der offenen Marknagelung);
  • Osteosynthesen (Goetze-Cerclagen, Zuggurtungen, Cerclagen, Hemicerclagen; die Indikation hierzu kann ausgedehnt werden, da eine feste Verankerung möglich ist);
  • Veränderung der distalen Kortikalisausbrüche bei der Federnagelung nach Ender und Simon-Weidner;
  • Unterstützung von Bandplastiken (Schulter-Eck-Gelenk, Sprunggelenk, Knie-Kreuzband);
  • Adaptation und Wiedervereinigung nach Osteotomien(z.B. Sternum, insbesondere auch bei Herzeingriffen: Trochanter major);
  • Erleichterung des Verschlusses der Thoraxwand durch stabile Adaptation benachbarter Rippen;
  • Verbesserung der Rippenosteosynthese, indem die üblichen Judet-Platten aus Kunststoff nachgebildet werden und die sonst zur Verankerung umgebogenen Metallamellen durch die erfindungsgemäßen Kunststoffbänder ersetzt werden.
The permanently tensionable plastic band according to the invention can be used in the surgery of the posture and musculoskeletal system, for example in the following cases:
  • Temporary fixation of frankings (eg with open intramedullary nailing);
  • Osteosynthesis (Goetze-Cerclagen, Zuggurtung, Cerclagen, Hemicerclagen; the indication for this can be extended because a firm anchoring is possible);

Das in Figur 1 in einer bevorzugten Ausführungsform gezeigte Kunststoffband 1 weist glatte Außenflächen auf; dies gestattet die stufenlose Anspannung des Kunststoffbandes 1 und damit die exakte Einstellung der gewünschten Zugspannung. Wenn gewünscht, kann das Kunststoffband 1 aber auch an einer oder mehreren Außenflächen mit einer Querriffelung versehen werden, wodurch die Halterung des Kunststoffbandes '1 unter Zugspannung verbessert werden kann. Das Kunststoffband 1 trägt an einem Ende eine Verdickung 2 , die unter Zugspannung des Kunststoffbandes 1 ein Gegenlager bildet. Das Kunststoffband '1 ist durch einen Spannippel 5 geführt, der zylindrisch ausgebildet ist oder sich konisch gegen die Spannrichtung 4 des Kunststoffbandes 1 verjüngt. Das Kunststoffband 1 ist an dem longitudinalen Endabschnitt geringeren Durchmessers des Spannippels 5 in diesen eingeführt und tritt an seinem longitudinalen Endabschnitt größeren Durchmessers wieder aus dem Spannippel 5 aus, wobei es einen Überstand 3 bildet. Dieser dient zum Spannen des Kunststoffbandes 1, z.B. zum Ansetzen geeigneter Spannwerkzeuge, und wird nach Erreichen der gewünschten Zugspannung abgeschnitten. Je nach Einsatzzweck des Kunststoffbandes 1 ist die an seinem Ende vorgesehene Verdickung 2 entweder so ausgestaltet, daß sie sich in Spannrichtung des Kunststoffbandes 1 konisch verjüngt oder zylindrisch ausgebildet ist oder ist als quer zur Längsrichtung des Kunststoffbandes 1 mit diesem fest verbundene flache Scheibe ausgebildet.The plastic strip 1 shown in FIG. 1 in a preferred embodiment has smooth outer surfaces; this allows the infinite tensioning of the plastic band 1 and thus the exact setting of the desired tension. If desired, the plastic tape 1 can also be provided with cross corrugation on one or more outer surfaces, whereby the holding of the plastic tape '1 under tension can be improved. The plastic tape 1 carries at one end a thickening 2, which forms a counter bearing under tension of the plastic tape 1. The plastic band '1 is guided through a clamping nipple 5, which is cylindrical is formed or tapers conically against the tensioning direction 4 of the plastic band 1. The plastic strip 1 is inserted into the clamping nipple 5 at the longitudinal end section of smaller diameter and emerges from the clamping nipple 5 again at its longitudinal end section, forming a protrusion 3. This is used for tensioning the plastic band 1, for example for attaching suitable tensioning tools, and is cut off after the desired tension has been reached. Depending on the intended use of the plastic tape 1, the thickening 2 provided at its end is either designed such that it tapers conically in the tensioning direction of the plastic tape 1 or is cylindrical or is designed as a flat disc which is firmly connected to the plastic tape 1 transversely to the longitudinal direction thereof.

Wie Figur 2 zeigt, weist der Spannippel 5 einen ihn in Längsrichtung durchsetzenden Bandkanal .6 auf, durch den das Kunststoffband 1 geführt werden kann. Dabei füllt es den Bandkanal 6 im wesentlichen aus, so daß ein störungsfreies Zusammenwirken von Kunststoffband 1 und Spannnippel 5 gewährleistet ist. Auf seiner Innenfläche ist der Spannippel 5 mit mehreren, in den Bandkanal 6 vortretenden Gesperrnasen oder -rippen 7 versehen, die in Spannrichtung 4 des Kunststoffbandes gesehen mit relativ geringer Steigerung in den Bandkanal 6 vortreten, gegen die Spannrichtung 4 gesehen aber im wesentlichen quer zur Spannrichtung 4 in den Bandkanal 6 vortretende Stufenflächen bilden. Da das Kunststaffband 1 den Bandkanal 6' im wesentlichen füllt, werden die Gesperrnasen 7 . beim Einführen des Kunststoffbandes 1 aus dem Bandkanal 6 zurückgedrängt, indem das Kunststoffband (1) an ihnen entlanggleitet. Die Gesperrnasen oder -rippen 7 pressen sich dabei in das Kunststoffband 1 ein. Das Kunststoffband 1 wird an einer Bewegung gegen die Spannrichtung 4 durch die Gesperrnasen 7 gehindert, die sich bei einer solchen Bewegung mit ihren Stufenflächen und deren Schärfen, in den Bandkanal 6 hervorragenden Kanten in das Kunststoffband 1 eingraben.As FIG. 2 shows, the tensioning nipple 5 has a band channel 6 passing through it in the longitudinal direction, through which the plastic band 1 can be guided. It essentially fills the band channel 6, so that a trouble-free interaction of the plastic band 1 and the clamping nipple 5 is ensured. On its inner surface, the clamping nipple 5 is provided with a plurality of locking noses or ribs 7 which appear in the band channel 6 and which, seen in the tensioning direction 4 of the plastic band, occur in the band channel 6 with a relatively small increase, but viewed against the tensioning direction 4, but essentially transversely to the tensioning direction 4 form step surfaces protruding into the band channel 6. Since the synthetic tape 1 essentially fills the tape channel 6 ', the locking tabs 7. pushed back out of the band channel 6 when the plastic band 1 is inserted by the plastic band (1) sliding along them. The locking lugs or ribs 7 are pressed into the plastic band 1. The plastic tape 1 is prevented from moving against the tensioning direction 4 by the locking lugs 7 which, in the case of such a movement, with their stepped surfaces and their sharpening, dig into the band channel 6 with excellent edges into the plastic band 1.

Ein abgewandelter Spannippel 5 ist in Figur 3 im Längsschnitt gezeigt. Er ist durch mehrere, von seinem verdickten Endabschnitt ausgehende Schlitze 9 auf einem Teil seiner Längserstreckung in Nippelsegmente 8 unterteilt. Beim Einsetzen des Spannippels 5 in eine Durchbohrung, wie unten an Hand der Figur 4 näher erläutert, wird der Spannippel 5 unter der Zugspannung des Kunststoffbandes 1 vom Umfang her zusammengedrückt. Dabei gestatten die Schlitze 9, daß die Nippelsegmente 8 unter Verengung des Bandkanals 6. einwärts geschoben werden und dabei, ähnlich wie die Gesperrnasen 7 des oben beschriebenen Spannippels 5, das Kunststoffband 1 festklemmen.A modified clamping nipple 5 is shown in longitudinal section in FIG. It is divided into several nipple segments 8 by a number of slots 9 extending from its thickened end section over part of its longitudinal extent. When the clamping nipple 5 is inserted into a through-hole, as explained in more detail below with reference to FIG. 4, the clamping nipple 5 is compressed from the circumference under the tension of the plastic band 1. The slots 9 allow the nipple segments 8 to be pushed inward while narrowing the band channel 6 and, similarly to the locking lugs 7 of the clamping nipple 5 described above, clamp the plastic band 1.

Zur Zuggurtung von Knochenfrakturen wird, wie Figur 4 schematisch zeigt, zunächst eine in etwa geradlinige Durchbohrung der unter Zugspannung zu verbindenden Knochenfragmente 12 a und 12 b vorgenommen. Nachfolgend wird das Kunststoffband 1 durch die Durchbohrung der Fragmente geführt, bis seine Verdickung 2 am Außenumfang des einen Knochenfragments 12 b in die Durchbohrung eintritt. Der Spannippel 5 wird auf das Überstandsende 3 des Kunststoffbandes 1 aufgeschoben, welches am Außenumfang des anderen Knochenfragments 12 a aus der Durchbohrung vortritt. Dabei weist sein konisch verjüngter longitudinaler Endabschnitt mit geringerem Durchmesser in Richtung auf die Verdickung 2.For tension banding of bone fractures, as shown schematically in FIG. 4, an approximately rectilinear perforation of the bone fragments 12 a and 12 b to be connected under tension is carried out first. The plastic band 1 is then passed through the perforation of the fragments until its thickening 2 on the outer circumference of the one bone fragment 12b enters the perforation. The clamping nipple 5 is pushed onto the protruding end 3 of the plastic band 1, which protrudes from the through hole on the outer circumference of the other bone fragment 12 a. Its conically tapered longitudinal end section with a smaller diameter points in the direction of the thickening 2.

Der Spannippel 5 wird nun auf dem Kunststoffband 1 soweit in Richtung auf die Fertigung .2 verschoben, daß sein Endabschnitt geringeren Durchmessers am Außenumfang des Knochenfragments 12 a ebenfalls in die Durchbohrung eintritt. Nachfolgend wird das Kunststoffband 1 gegenüber dem Spannippel 5 solange in Spannrichtung 4 angezogen, bis die für die Zuggurtung gewünschte Zugspannung erreicht ist. In dieser Stellung wird es entweder durch die Gesperrnasen 7 oder durch die Nippelsegmente 8 festgeklemmt. Die über die Außenumfangsflächen 10,11 der Knochenfragmente 12 a bzw. 12 b vortretenden Teile des überstands 3 des Kunststoffbands 1 und des Spannippels 5 einerseits, der Verdickung 2 andererseits können jetzt so abgeschnitten werden, daß sie mit den Außenumfangsflächen der Knochenfragmente 12 a bzw. 12 b fluchten. Es versteht sich, daß der Spannippel 5 so mit Gesperrnasen ,7 bzw. Schlitzen .9 und dadurch gebildeten Nippelsegmenten 8 versehen sein muß, daß ein sicheres Einklemmen des Kunststoffbandes 1 durch den Bereich des Spannippels 5 gewährleistet ist, der sich innerhalb der Durchbohrung des Knochenfragments 12 befindet.The clamping nipple 5 is now moved so far on the plastic band 1 in the direction of the production .2 that its end portion of smaller diameter on the outer circumference of the bone fragment 12 a also enters the through hole. Subsequently, the plastic band 1 is tightened relative to the tensioning nipple 5 in the tensioning direction 4 until the tension required for the tension belt is reached. In this position, it is clamped either by the locking lugs 7 or by the nipple segments 8. The parts of the protrusion 3 of the plastic band 1 and the clamping nipple 5 that appear on the outer circumferential surfaces 10, 11 of the bone fragments 12 a and 12 b, on the one hand, and the thickening 2 on the other hand can now be cut off so that they match the outer circumferential surfaces of the bone fragments 12 a or 12 b are aligned. It goes without saying that the clamping nipple 5 must be provided with locking lugs, 7 or slots .9 and nipple segments 8 formed thereby in such a way that a secure clamping of the plastic band 1 is ensured by the area of the clamping nipple 5 which is located within the hole in the bone fragment 12 is located.

Im folgenden wird eine zweite bevorzugte Ausführungsform des Kunststoffbandes 1 näher erläutert, die für umgreifende Cerclagen ausgelegt ist. Bei dieser in Figur 5 gezeigten bevorzugten Ausführungsform ist das Kunststoffband 1 an einem Ende fest mit dem in Spannrichtung hinteren Endabschnitt 14 des Spannippels 13 verbunden. Der Spannnippel 13 muß bei dieser Ausführungsform nicht konisch sein, sondern kann vielmehr einen über seine Längserstr-eckung gleichbleibenden Durchmesser aufweisen. Er ist bevorzugt so ausgebildet, daß eine glatte Anlagefläche an den zu halternden Knochen gebildet wird. Er ist z.B. auch abgeflacht ausgebildet.In the following a second preferred embodiment of the plastic tape 1 is explained, which is designed for encompassing cerclages. In this preferred embodiment shown in FIG. 5, the plastic tape 1 is firmly connected at one end to the rear end section 14 of the clamping nipple 13 in the tensioning direction. In this embodiment, the clamping nipple 13 does not have to be conical, but rather can have a diameter that is constant over its longitudinal extension. It is preferably designed so that a smooth contact surface is formed on the bones to be held. It is e.g. also flattened.

Wie Figur 6 zeigt, wird der Spannippel 13 ebenfalls von einem Bandkanal 6 in Längsrichtung durchsetzt; das dauerelastische Kunststoffband 1 wird zur Anlegung der Cerclage um die zu verbindenden Teile (z.B. Knochenfragmente) geführt und dann mit seinem freien Ende in den in Spannrichtung 4 vorderen Endabschnitt 15 des Spannippels 13 eingeführt. Dieser ist auf seiner Innenfläche mit wenigstens einer in den Bandkanal 6 vortretenden, das eingeführte Kunststoffband 1 an einer Bewegung gegen die Spannrichtung 4 hindernden Gesperrnase 7 versehen. Nach Anliegen des Kunststoffbandes 1 wird dieses, z.B. durch Ansetzen eines geeigneten Werkzeugs an den aus dem Endabschnitt 14 des Spannippels ,13 austretenden überstand.3, solange gegenüber dem Spannippel'13' angezogen, bis es sich unter Erreichen der gewünschten Zugspannung fest an den Außenumfang der zu verbindenden Teile angelegt hat.As Figure 6 shows, the clamping nipple 13 is also penetrated by a band channel 6 in the longitudinal direction; The permanently elastic plastic band 1 is guided around the parts to be connected (e.g. bone fragments) to apply the cerclage and then inserted with its free end into the front end section 15 of the clamping nipple 13 in the tensioning direction 4. This is provided on its inner surface with at least one locking lug 7 protruding into the band channel 6 and preventing the inserted plastic band 1 from moving against the tensioning direction 4. After the plastic tape 1 has been applied, this is e.g. by attaching a suitable tool to the protrusion 3 emerging from the end section 14 of the clamping nipple, 13 until the clamping nipple'13 'has been tightened until it has firmly attached itself to the outer circumference of the parts to be connected when the desired tension has been reached.

Der Spannippel 13 wird in eine vorher geschaffene Vertiefung im Außenumfang eines der unter Zugspannung zu verbindenden Teile eingelassen und dadurch in diesem gegen ein Verschieben gesichert. Seine nach außen gewandte Fläche kann so abgeflacht und ggf. gekrümmt sein, daß der Spannippel 13 nur unwesentlich über den Außenumfang des Teils vorsteht.The clamping nipple 13 is inserted into a previously created recess in the outer circumference of one of the parts to be connected under tensile stress and is thereby secured against displacement in the latter. Its outward-facing surface can be flattened and, if necessary, curved so that the clamping nipple 13 projects only insignificantly over the outer circumference of the part.

Das Kunststoffband 1 wie auch der Spannippel 5,13 bestehen aus biokompatiblem Material. Es kann vorgesehen werden, diese Teile aus resorbierbaren Polymeren auszubilden, so daß sie nach Verheilen der Fraktur vom Körper resorbiert werden. Andererseits lassen sich das Kunststoffband 1 und der Spannnippel 5 auch aus dauerkompatiblem Material anfertigen, beispielsweise aus dem im Handel unter der Bezeichnung "Gortex" erhältlichen Material, das beim Heilungsprozeß von Knochensubstanz durchwachsen wird und auf Dauer im Körper verbleiben kann.The plastic band 1 as well as the clamping nipple 5.13 are made of biocompatible material. Provision can be made for these parts to be made from resorbable polymers so that they are resorbed by the body after the fracture has healed. On the other hand, the plastic band 1 and the clamping nipple 5 can also be made from permanently compatible material, for example from the material commercially available under the name "Gortex", which is grown through during the healing process of bone substance and can remain in the body in the long run.
